Symptoms

1st problem:
Taking a screenshot makes the game permanently dark until its restart.

Before taking the screenshot:

After taking the screenshot:

2nd problem:
The mouse cursor is invisible when Steam overlay is open.

3rd problem:
The mouse cursor is invisible when alt-tabbed to desktop.

Reproduction

1st problem:
Launch the game, use the key to take a screenshot in Steam (default F12). The game will become dark after that.

2nd problem:
Launch the game. Press Shift+Tab to open Steam overlay. The mouse cursor will be invisible while the overlay is active.

3rd problem:
Launch the game. Press Alt+Tab to switch to desktop. The mouse cursor will be invisible while alt-tabbed.

Start with the attached steam-63660-taking-screenshot.log and steam-63660-open-overlay-and-alt-tab.log, then reproduce the three symptoms with Proton 3.16-1. Verify whether current Proton still shows the screenshot-darkening and invisible-cursor behavior. The report names no source file or test, so a completed fix and regression coverage would first require identifying the relevant subsystem.
